The April 8, 2024, eclipse was a total solar eclipse. It was the last total solar eclipse visible from the contiguous United States until 2044.

A total solar eclipse happens when the Moon passes between the Sun and Earth, completely blocking the face of the Sun. People viewing the eclipse from locations where the Moon’s shadow completely covers the Sun — known as the path of totality — will experience a total solar eclipse. The sky will darken, as if it were dawn or dusk. Weather permitting, people along the path of totality will see the Sun’s corona, or outer atmosphere, which is usually obscured by the bright face of the Sun.

The April 8, 2024, total solar eclipse began over the South Pacific Ocean and crossed North America, passing over Mexico, the United States, and Canada.

Weather permitting, the first location in continental North America that experienced totality was Mexico’s Pacific coast at around 11:07 a.m. PDT.

The path of the eclipse continued from Mexico, entering the United States in Texas, and traveling through Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire, and Maine. The eclipse entered Canada in Southern Ontario, and continued through Quebec, New Brunswick, Prince Edward Island, and Nova Scotia. The eclipse exited continental North America on the Atlantic coast of Newfoundland, Canada, at 5:16 p.m. NDT.

On April 8, 2024, participants both in and outside the eclipse path joined NASA to learn more about our Sun and Earth and the effects of a total solar eclipse.

From cell phone apps to use on April 8 to recording the sounds of the eclipse, there are opportunities for anyone to get involved with studying this celestial event.
